Question

I have an array of labels

[labelsArray objectAtIndex:1] ????

I want to change label text style to bold and stressed. How can I do that?

Answer 1

I do not understand what you mean by stressed but if you want to make it bold you can write:

UILabel *label = [labelArray objectAtIndex:1];
label.font = [UIFont fontWithName:@"Helvetica-Bold" size:18];

The size and font type is ofcourse up to you.

EDIT for comment:
I have never done that, but after some searching I found this post at stackoverflow. You may try that, but there is no “built-in” function for this as far I know.
